Excerpt: I had these for one year before the sound seemed to "drop" in volume/quality on the right side. However, I had been frustrated with them for quite awhile before then due to their shortcomings in design.
Summary: I love these headphones as they are among the best I have heard (noob right?). I would compare these headphones to sound the same as Beats by Dre Pro Headphones with slightly less emphasis on the bass. Now they have great quality overall but more bass oriented. I found the bass to have good transparency until I listened to more modern music which i found it to be slightly over powering.
Amp is completely unnecessary.
Pros: Isolation, Build Quality, Warranty, Case, Amount of Tips
Summary: Bass is slightly boosted with a bit of extra warmth thrown in, but nowhere near the amount present in IE8.
Mids sound a bit aggresive with some 3.5k boost.
Highs are present, though not exactly delicate. Some 6k hump exists. Extension is ok, but the highest lack volume.
In general, the response is bass oriented, which is easy to correct with an equalizer. Timbre is a bit fat on this one.
Pros: Excellent comfort, cable and build quality, good sound quality overall
Cons: Bass-slanted and warm sound, slight veil, over-the-ear only, too "fat" timbre, possible fit issues for people with small ears
Summary: DISCLAIMER: I am not an audiophile. I am an audio appreciator. I hope.
I had these for one year before the sound seemed to "drop" in volume/quality on the right side. However, I had been frustrated with them for quite awhile before then due to their shortcomings in design.
I give this an overall positive value simply because the sound on these is really quite good.
High - Clean
Mid - Full, rich, good body, well produced
Bass - Good.
Summary: These are normally over $400 on Amazon, where I got them for $100 "opened, but unused" with high expectations corresponding to the $400 price. They had all the tips, but with two mounted on the 'phones and four in the case; no grill cleaner. The problem I found, but which bothers me a lot, is that the highest notes on one of my favorite recordings, Philip Glass's Mishima soundtrack (which is like a tuneful test record), sound like a clicking, not ringing.
Pros: Most of frequency range.
Cons: Very high frequency notes sound dull, like hitting metal rods together. Mechanically: short penetration; hard to stay in.
Summary: IE7 is meant to be a clear sounding dynamic with decent bass. As dynamic drive, it needs burn-in for at least 100 hour of music or shorter time with pink and white noise. the sound is so great and the bass is strong and tight after burn-in. don't let so earphone purposely tune for super high bass fool you. they waste the music because all you hear is bass. This earphone let you enjoy every aspect of music not just bass.
Pros: Compact, Durable, Good Bass, Lightweight, Rich Sound
Summary: Great sound. The fit is that it lays in the bottom of your ear. Wire goes over back of ear. The silicon eartips fit only slightly in the opening in the ear rather than fitting deep into ear canal. A proper seal is absolutely essential to get a decent bass response for earphones that fit into the ear rather than over the ear (headphones). It works for me (just barely)without fitting deep into my ear canal. Despite this unusual fit, they are really very comfortable.
